Question

I’m using redis lists and pushing to new items to a list. The problem is I really only need the most recent 10 items in a list.

I’m using lpush to add items to a list and lrange to get the most recent 10.

Is there anyway to drop items after a certain number? I’ll end up with lists that may have 1,000’s of items and can cause performance issues with latency.

Thank you!

Answer 1

After every lpush, call ltrim to trim the list to 10 elements

See http://redis.io/commands/ltrim
